English: Late WWII German flak. NOTE: The image is most likely published in Germany between mid-1944 to mid-1945. An image belongs to the public domain 70 years after it was published, even though I cannot find its original photographer (one of the German weapon workers?). It was definitive that the weapon entered production in late 1944 and production ended before mid-1945, so the photograph of this weapon system would have been taken earlier than mid-1945, or possibly even earlier than mid-1944 if it was a prototype. Since no known example of such weapon survived, all photographs of this weapon was assumed to be taken in Germany during WWII. For further information see: en:3_cm_M.K._303_Flak.
